Linear gate installation in San Jose typically runs $1,150 to $4,200 depending on the gate style, actuator model, and whether we’re mounting on new posts or retrofitting an existing gate. Most single-swing driveway gates land between $1,400 and $2,600 for a complete Linear operator install with safety edges, and we’ll have a written price in your hand before any work begins. As an independent Linear service provider, we install and service the full range of Linear gate operators across San Jose, from light residential swing arms to heavier sliding gate systems.
If you own a Linear unit that needs replacing, or you want a Linear operator on a new gate, this page covers what actually happens on the job, what it costs, and what tends to go wrong with Linear hardware in the San Jose climate. Call (669) 800-5686 and you’ll reach a live person, not a voicemail tree.
How Linear Products Fail – and How We Fix Them
Linear makes dependable gate operators, but Dean Prescott and our crew have pulled enough of them apart in San Jose to know exactly where the wear concentrates. Here are the five failure patterns we see most often on Linear gate installations, and what we do about each one.
- Linear LRA swing-arm actuator clutch slip. The LRA series swing arms use an internal clutch that starts slipping after years of wind loading against the gate leaf. The symptom is a gate that opens halfway, groans, and reverses. Many shops replace the whole arm. We usually replace the clutch assembly and re-torque the arm to spec, which saves $400 to $600 over a full arm swap and leaves the original motor intact.
- Linear Mighty Mule FM502 control board relay failure. The FM502 is common on San Jose double gates, and its open relay burns out when the gate leaf binds against a shifting post or a sagging hinge. The board clicks but the gate doesn’t move. We replace the relay or board, then correct the hinge or post alignment that caused the overload in the first place. Skip the second half and the new board fails the same way.
- Linear APeX series limit switch drift. The APeX sliding gate operators use exposed limit switches that collect Valley dust and slowly drift out of position. The gate stops six inches short of closed, or overdrives and slams the stop. We clean, recalibrate, and seal the limit assembly, and replace the switch if the actuator arm is worn. This is one of the most common calls we get from customers whose previous gate company couldn’t figure out why the gate kept losing its closed position.
- Linear LS050 gearbox wear from Bay Area moisture and thermal cycling. South Bay mornings are damp, afternoons are warm, and over a decade that cycle lets condensation work into the LS050 sliding gate gearbox. The grease thins, the output shaft wears, and the gate starts grinding on every open. We rebuild or replace the gearbox, and we always ask how old the chain is while we’re in there, because a stretched chain accelerates gearbox wear on every cycle.
- Linear M3 solar operator charging failures from partial shade. The M3 and similar Linear solar units are popular on San Jose hillsides where running AC power isn’t practical, but San Jose’s mature oak and redwood canopies often shade the panel for part of the day. The panel undercharges, the battery voltage sags, and the operator starts opening slowly or not at all. We re-site the panel where possible, test the charge controller, and swap the battery when it won’t hold a load.

Our Linear Gate Installation Process
Every Linear installation in San Jose follows the same sequence, and we tell you the price before step one starts. Here’s what to expect when you call Portcullis Gate Repair San Jose.
- 1
You call, we answer. A live person takes your address, gate type, and which Linear model you have or want. If you don’t know the model, we can identify it from photos you text over.
- 2
Free on-site measure and diagnostic. We check the existing gate, posts, hinges, and power situation. For new gates, we measure the opening, weight the leaf, and confirm which Linear operator series is right for the duty cycle.
- 3
Written quote with an honest parts decision. Every quote names the part and says whether we recommend Linear OEM or a quality aftermarket equivalent. OEM preserves the manufacturer warranty; aftermarket often matches performance for less. We give you both numbers and let you choose.
- 4
Installation day, within the window we gave. Our background-checked, uniformed technicians arrive in the window on the quote. We mount the operator, run and land the low-voltage wiring, set travel limits, and install the required safety edges and photo sensors.
- 5
Test cycle in front of you, then clean the site. We run the gate through open, close, obstruction-stop, and battery-backup (where fitted) routines. Then we sweep, gather our materials, and leave the gate area cleaner than we found it.
- 6
Written Kingswell Guarantee on the invoice. Every installation and repair carries the 365-Day Done Right Promise in writing. If anything fails inside that window, we come back and fix it at no charge.

AfterWhat Linear Gate Installation Costs in San Jose
Here are the honest ranges we quote across San Jose, including the Almaden Valley, Willow Glen, Evergreen, and Berryessa neighborhoods. These are parts and labor together, quoted before any work starts.
| Job | Typical Range | Notes |
|---|---|---|
| Single swing gate, Linear actuator replacement | $1,400 – $2,600 | Includes arm, control board, safety edges, labor |
| Double swing gate, dual Linear LRA operator | $2,800 – $4,200 | Two arms, master/slave setup, edge controls |
| Sliding driveway gate, Linear APeX or LS050 install | $2,200 – $3,800 | Operator, chain, safety, travel limits |
| Pedestrian gate, Linear Mighty Mule or M3 | $1,150 – $1,900 | Lighter-duty operator, same safety standards |
What moves the price: gate weight exceeds the operator’s duty rating and requires a larger unit, existing posts need shoring or replacement, power isn’t already at the gate and a low-voltage run or solar system is required, or the old operator wiring isn’t up to code and needs repulling. You’ll always know the total before we start. Call (669) 800-5686 and we’ll send someone out for a free measure and written estimate.
Why San Jose Homeowners Call Portcullis Gate Repair San Jose for Linear Work
Most of the customers who call us for Linear gate installation in San Jose have already tried another shop. The pattern is usually the same: a tech shows up late or not at all, the quote moves once the gate is taken apart, or the fix fails a month after the truck leaves. We’re built around the opposite of that. Dean Prescott has been doing this long enough to know that the customer’s second fear, right behind the gate not working at all, is an invoice larger than the number they were first told. That’s why the price is in writing before a single bolt is turned.
Every job, including every Linear install, carries the 365-Day Done Right Promise. If it fails within a year of the repair, we return and correct it at no charge. That’s written on the invoice, not implied. We also service the other operators you might have on the property: LiftMaster, Mighty Mule, Ghost Controls, and DoorKing. One call covers the whole property.
FAQs
No, an independent installation doesn’t void the Linear manufacturer warranty on the operator itself, provided the install meets the manufacturer’s installation requirements and the operator isn’t modified. We install to Linear’s specs and keep records of every job. If a warrantied Linear part fails later, we can document the install for your claim.
Most single-gate Linear installations are scheduled within a few days, and the install itself takes a half day to a full day. New gate construction or jobs requiring new posts, concrete, or power runs are measured and scheduled rather than rushed, with a written price and arrival window before we start.
If the operator is under 8 years old and the failure is a control board, limit switch, or clutch, repair is usually the smarter spend. If the gearbox is worn, the arm is corroded through, or the operator is over 12 years old, replacement often costs less over the next five years than repeated repairs. We’ll give you both numbers and a straight recommendation.
Yes. We run and land low-voltage power, install the required safety edges and photo sensors, set travel limits, and test obstruction stops. For gates far from AC power, we’ll check whether a solar Linear setup like the M3 is practical for your San Jose site’s shade exposure.
If the repair or installation fails within 365 days for any reason related to the work we did, we come back and fix it at no charge. The promise is printed on your invoice, and the second visit is free. Call (669) 800-5686 and we’ll make it right.
